Wood Nuts Master: Screw Puzzle

One wrong screw and the whole wooden stack just sits there, smug and unmoved, while you stare at your dwindling holes. That's the tension running through Wood Nuts Master: Screw Puzzle - a physics-based puzzle where the goal is deceptively simple: place screws and nuts so the wooden blocks fall.

The catch is those empty holes don't stay empty for long. Fill the wrong one early and you might seal off the exact spot you needed two moves later. So you end up scanning the board, weighing every socket before committing, which is exactly the kind of low-key strategic thinking fans of Brain Training Games tend to enjoy.

It runs right in your browser on desktop, Android or iOS, no download needed, so you can chase that satisfying toppling moment on whatever screen is in front of you. If you like puzzles that reward patience over speed, it sits comfortably alongside other Puzzle games on the site, and it scratches a similar itch to Mind Games built around spotting the one move that unlocks everything else.

Place screws and nuts into the empty holes so every wooden block falls. That's the whole objective, and it sounds easier than it plays out.

Tap or click a hole to place a screw. Each block needs the right support removed or added in the right order, and holes can get covered up as you go, so a spot you were saving might vanish before you use it.

Before you tap anything, scan the whole board first. Committing to the first open hole you see is how you end up boxed in with blocks still standing and nowhere left to place a screw.
